Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible to likely across much of Southern New England Sunday Afternoon and Evening. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats. The Storm Prediction Center (SPC) has all of Southern New England in a slight risk for severe weather for Sunday. Threat timeframe is between 12-8 PM Sunday..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely as the potential strong to severe thunderstorms traverse the region Sunday Afternoon and Evening. Pictures and videos of storm damage can be sent as a reply to this message, via our WX1BOX Facebook and Twitter feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

We will be posting updated post severe weather coordination messages on the prior severe weather events over the course of this weekend. We appreciate and thank all Amateur Radio and non-Amateur Radio SKYWARN Spotters for the reports, pictures and videos during those events and if there is more data available, please feel free to send it along to us.

Turning our attention to Sunday’s severe weather potential, the headlines depict the current thinking and as we get closer to the severe weather potential, we will have a better idea of coverage and intensity. The key factors to dictating the coverage and intensity include:

1.) Amount of heating and destabilization we receive ahead of a strong cold front after any morning showers and thunderstorms clear the region.
2.) Shear profiles will be very strong. If heating and destabilization is somewhat less than expected, the strong winds aloft may offset to some extent lesser instability.
3.) Cold frontal timing which is currently expected to be in the ideal time range to maximize heating and destabilization.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely as the potential strong to severe thunderstorms traverse the region Sunday Afternoon and Evening. Pictures and videos of storm damage can be sent as a reply to this message, via our WX1BOX Facebook and Twitter feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated. Another coordination message will be posted either by 11 PM Saturday Evening or 11 AM Sunday Morning depending on changes to the forecast and other factors.

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms remain possible late Wednesday Afternoon into late Wednesday Night particularly over Western Massachusetts and Northern Connecticut but all of interior Southern New England should monitor the potential. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats..
..The Storm Prediction Center (SPC) has placed Southern New England in a marginal risk for severe weather. Severe weather potential will be after 4-11 PM Wednesday give or take a few hours. There could be some activity that starts earlier in the evening and also some activity beyond 11 PM into the overnight hours..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible for the severe weather potential..

Heat and Humidity will return on Wednesday in the region followed by a cold front. This cold front will not be ideally timed to take advantage of maximum instability, however, strong wind shear and other factors may allow for at least an isolated severe thunderstorm threat. The headlines depict the current thinking. Key factors remain:

1.) If the timing of the front were to speed up and be closer to the higher instability levels, the severe weather potential would increase.
2.) If a complex of severe thunderstorms were to form out west, the storms may maintain themselves better as they enter our region especially in Western Massachusetts and Northern Connecticut even with the current timing.
3.) If wind shear and other factors are able to offset lowering instability to produce at least isolated severe thunderstorms with the current timing.
4.) There could also be some activity with the pre-frontal trough in the mid to late afternoon but shear profiles won’t be as strong and there could be other mitigating factors such as lack of moisture in the mid to upper levels but this will also bear watching this afternoon and evening.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible for the severe weather potential. This will be the last coordination message as we move into operations mode.

Hello to all…

..The following is the fourth in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 20 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..A higher end severe weather event/outbreak is likely today, Sunday, in Western and Central Massachusetts and Northern Connecticut with other portions of interior Southern New England north and west of a Boston to Providence line also likely to see severe weather today. Amateur Radio Field Day sites in the region should be on high alert and have multiple ways to receive weather information as the Field Day operation winds down Sunday Afternoon into early evening..
..The Storm Prediction Center (SPC) has placed Western and Central Massachusetts in Enhanced Risk for severe weather today with a slight risk for severe weather in Connecticut, Eastern Massachusetts and much of Rhode Island with a Marginal Risk for severe weather for the rest of Southern New England. Threat timeframe is from 1-10 PM Sunday. Storm coverage today is expected to be the highest of this 5 day stretch of severe weather with potential for higher end severe weather today over a wider area..
..Strong to damaging winds, isolated tornadoes, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats for Sunday with the main risk area in interior Southern New England north and west of a Boston to Providence line..
..A Heat Advisory remains in effect through 7 PM Sunday Evening for Northern Connecticut, Eastern Hampden and Eastern Hampshire Counties of Massachusetts for heat indices to 97 degrees..
..Any thunderstorms have lightning potential which is a safety hazard for all Amateur Radio Field Day sites. Amateur Radio Field Day sites are encouraged to guard their local Amateur Radio SKYWARN frequency and have multiple ways to receive weather alerts during the course of this Field Day weekend including by cell phone/Internet and NOAA Weather Radio..
..Amateur Radio Field Day Weekend is an annual event where Ham Operators across the United States setup at Emergency Operations Centers, field locations, home locations etc. to operate and test their equipment and skills and make as many radio contacts as possible during the weekend..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Sunday Afternoon and Evening in interior Southern New England for the severe weather and flood potential and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend. Pictures, videos and storm damage reports from today or this stretch of severe weather from Wednesday through Saturday can be sent as a reply to this message via our WX1BOX Facebook and Twitter feeds or via the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..
..Saturday’s severe weather event along with the severe weather events from Wednesday through Friday are covered after messaging about Sunday’s potential severe weather outbreak..

Here are some links to information on these Amateur Radio Field Day Sites from across the region.

Eastern Massachusetts Field Day Home Page: https://ema.arrl.org/field-day/
Eastern Massachusetts Field Day Directory: https://ema.arrl.org/field_day/

As we close out Amateur Radio Field Day weekend, we have the potential for a higher end severe weather outbreak in much of interior Southern New England as a stronger cold front that is a stronger triggering mechanism, strong wind shear profiles coupled with similar levels of instability as we have seen the last few days to result in a potential severe weather outbreak with all modes of severe weather, damaging winds, hail, isolated tornadoes and heavy rainfall leading to urban and poor drainage flooding are potential threats. The timeframe is from 1-10 PM Sunday Afternoon and Evening as Amateur Radio Field Day winds down and takedown of field setups will be occurring.

The severe weather could come in one long round of activity or be in two rounds with activity ahead of the front that will be more discreet cells followed by a line of severe thunderstorms with the actual cold front. This will evolve as we go through the day today.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Sunday Afternoon and Evening in interior Southern New England for the severe weather and flood potential and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend.

Amateur Radio Field Day sites are encouraged to bring a NOAA All-Hazards Weather Radio, monitor various cell phone weather apps where Amateur Operators may have those available and have a dedicated Ham Radio that can monitor their local SKYWARN frequency for their area as a best safety and preparedness practice as there is a threat for thunderstorm development and any thunderstorm can be a threat to the safety of Amateur Radio Field Day sites. Also sites that have mobile Internet capability can utilize that capability as a way to monitor for weather information. With Mobile Internet capability, utilizing Echolink to monitor the New England Reflector system on Echolink Conference *NEW-ENG3* Node: 9123/IRLP 9123 would be helpful as well. Please see the link below for the latest SKYWARN Frequency information for the region:
https://wx1box.org/southern-new-england-skywarn-frequency-list/

During setup and takedown of Amateur Radio Field Day sites and even while operating, be sure to drink plenty of fluids and eat accordingly. The link below features information on Heat Safety:
https://www.weather.gov/safety/heat

With the thunderstorm threat for this weekend, now is the time to remind folks that lightning is a threat to any and all Amateur Radio Field Day sites. Remember your lightning safety tips and details on lightning safety can be seen at the following link and we have also added a link from last year’s NWS Boston/Norton Lightning Safety Awareness Week and Public Information Statements on Lightning Safety from both 2023 and 2024. See links below:

Hello to all…

..The following is the third in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 20 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..This year’s Amateur Radio Field Day Weekend will feature the risk for Isolated to Scattered Strong to Severe Thunderstorms for Saturday and Sunday. It will remain warm and humid over most of Southern New England with some relief in Northeast Massachusetts Saturday before warm and humid conditions resume there for Sunday..
..A Heat Advisory is now in effect through 7 PM Sunday Evening for Northern Connecticut, Eastern Hampden and Eastern Hampshire Counties of Massachusetts for heat indices to 97 degrees..
..The Storm Prediction Center (SPC) has placed Western and Central Massachusetts, Connecticut and interior Rhode Island in a Marginal Risk for severe weather for Saturday. Threat timeframe is from1-8 PM Saturday. Storm coverage is expected to be similar to Friday and perhaps slightly stronger if enough sun and heating for instability and destabilization is realized with slightly stronger wind shear profiles aloft..
..SPC has placed Western and North-Central Massachusetts and Northwest Connecticut in a slight risk for severe weather Sunday with the rest of Southern New England in a marginal risk for severe weather. Rough timing window for this potential is 1-10 PM Sunday and will be fine-tuned in future updates..
..Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats this weekend but an isolated brief tornado cannot be ruled out for Saturday and an isolated tornado risk exists Sunday in the slight risk area of Western and Northwest Massachusetts and Northwest Connecticut and will be monitored closely..
..At this time, not every Field Day site will see a shower, thunderstorm or severe weather and a widespread washout is not expected. Some Field Day sites could be dry all weekend but other Field Day sites could be quite wet depending on where showers and thunderstorms develop. This will be monitored throughout the weekend..
..Any thunderstorms have lightning potential which is a safety hazard for all Amateur Radio Field Day sites. Amateur Radio Field Day sites are encouraged to guard their local Amateur Radio SKYWARN frequency and have multiple ways to receive weather alerts during the course of this Field Day weekend including by cell phone/Internet and NOAA Weather Radio..
..Amateur Radio Field Day Weekend is an annual event where Ham Operators across the United States setup at Emergency Operations Centers, field locations, home locations etc. to operate and test their equipment and skills and make as many radio contacts as possible during the weekend..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Saturday and Sunday Afternoon and Evening in interior Southern New England for the severe weather and flood potential and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend..

As we enter into Amateur Radio Field Day weekend, the thunderstorm and greatest severe weather potential will be across Western and Central Massachusetts, Northern Connecticut and Western Rhode Island for Saturday similar to how Friday was and this is on the warm end of the frontal boundary draped across the area. For Sunday, all of Southern New England has the potential for thunderstorms and severe weather with the greatest risk in the slight risk for severe weather area across Western and North-Central Masachusetts and Northwest Connecticut. This potential will be monitored closely as it may overlap with the end of Field Day weekend and the takedown of Amateur Radio station sites. Here is a breakdown of potential hazards by each day:

Saturday Afternoon and Evening:
Clouds and fog are burning off from west to eat which should allow for the heating and destabilization necessary to initiate severe thunderstorm development in the Marginal Risk for severe weather area. There is a bit more wind shear than the prior severe weather days and if the instability can develop with heating, it will set the stage for severe weather coverage similar to Friday in a similar area as yesterday. Threat timeframe is 1-8 PM which is also similar to Friday.

Sunday Afternoon and Evening:
This could be a day where much of Southern New England has severe weather potential and there is increasing risk for severe weather particularly in interior Southern New England with the greatest threat in Western and North-Central Massachusetts and Northern Connecticut. Wind shear profiles appear even stronger Sunday versus earlier in the week. The threat timeframe right now is between 1-10 PM Sunday and will be fine-tuned in the next coordination message and the headlines depict the current severe weather risk area for Southern New England.

While not as hot as earlier in the week, it will still be warm and humid for outdoor activities over the Field Day weekend period so Field Day sites should have plenty of liquids on hand and a place nearby to cool down whether it be a building or cars with AC to stay cool from the heat. Heat tips and safety guidelines are also included in this message. Northeast Massachusetts will have the most relief from the heat Saturday but the heat will return there as we get into Sunday.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Saturday and Sunday Afternoon and Evening in interior Southern New England for the severe weather and flood potential and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend.

Amateur Radio Field Day sites are encouraged to bring a NOAA All-Hazards Weather Radio, monitor various cell phone weather apps where Amateur Operators may have those available and have a dedicated Ham Radio that can monitor their local SKYWARN frequency for their area as a best safety and preparedness practice as there is a threat for thunderstorm development and any thunderstorm can be a threat to the safety of Amateur Radio Field Day sites. Also sites that have mobile Internet capability can utilize that capability as a way to monitor for weather information. With Mobile Internet capability, utilizing Echolink to monitor the New England Reflector system on Echolink Conference *NEW-ENG3* Node: 9123/IRLP 9123 would be helpful as well. Please see the link below for the latest SKYWARN Frequency information for the region:

Hello to all..

..The following is the second in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 20 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..This year’s Amateur Radio Field Day Weekend will feature the risk for Isolated to Scattered Strong to Severe Thunderstorms for Friday, Saturday and Sunday. It will remain warm and humid over most of Southern New England with some relief in Northeast Massachusetts Friday Afternoon into Saturday before warm and humid conditions resume there for Sunday. A Heat Advisory remains in effect through 7 PM for Northern Connecticut, Hampden, Hampshire Counties of Massachusetts for heat indices to 95 degrees.
..The Storm Prediction Center (SPC) has placed Western and Central Massachusetts, Connecticut and interior Rhode Island in a Marginal Risk for severe weather Friday. Threat timeframe between 1-8 PM Friday. SPC has placed Western, Central and interior Northeast Massachusetts and Northern Connecticut in a marginal risk for severe weather Saturday. Threat timeframe 1-8 PM Saturday as well. SPC has placed all of Southern New England in a marginal risk for severe weather. Timing will be better known for Sunday’s severe weather potential on Saturday..
..Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats this weekend..
..At this time, not every Field Day site will see a shower, thunderstorm or severe weather and a widespread washout is not expected. Some Field Day sites could be dry all weekend but other Field Day sites could be quite wet depending on where showers and thunderstorms develop. This will be monitored throughout the weekend..
..Any thunderstorms have lightning potential which is a safety hazard for all Amateur Radio Field Day sites. Amateur Radio Field Day sites are encouraged to guard their local Amateur Radio SKYWARN frequency and have multiple ways to receive weather alerts during the course of this Field Day weekend including by cell phone/Internet and NOAA Weather Radio..
..Conditions will be warm and humid Friday through Sunday though not as hot as earlier this week particularly in areas of Northeast Massachusetts which will have less heat and humidity Friday and into Saturday before becoming warm and humid again. Portions of Western Massachusetts, Northern Connecticut and Northern Rhode Island may continue to have heat similar to the previous days through Friday before conditions cool slightly Saturday but remain warm and humid over this time period..
..Amateur Radio Field Day Weekend is an annual event where Ham Operators across the United States setup at Emergency Operations Centers, field locations, home locations etc. to operate and test their equipment and skills and make as many radio contacts as possible during the weekend..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Friday Afternoon and Evening in interior Southern New England for the severe weather and flood potential and possible Saturday through this weekend. SKYWARN Self-Activation will monitor conditions throughout Field Day weekend and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend..

For Friday as we enter into Amateur Radio Field Day weekend, the thunderstorm and greatest severe weather potential will be across Western and Central Massachusetts, Northern Connecticut and North-Central Rhode Island. For Saturday, the greatest severe weather potential is Western, Central and interior Northeast Massachusetts and Northern Connecticut and for Sunday all of Southern New England has the potential for thunderstorms and severe weather. Here is a breakdown of potential hazards by each day:

Friday Afternoon and Evening:
The Severe Thunderstorm potential maybe a bit more isolated, perhaps similar to Wednesday of this week. It will be dependent on the frontal position that will bring cooler air into Northeast Massachusetts and amount of shear that overlaps with greater instability in the marginal risk area. Threat timeframe is 1-8 PM. In addition to the severe weather and lightning potential, flooding from very heavy downpours will bear close watching for flooding issues in areas that get repeated downpours.

Saturday Afternoon and Evening:
This will depend on what occurs Friday and if the front that will be over the region separating warmer and more humid air from somewhat cooler air shifts northeast or holds its current position. If it shifts northeast, much of Southern New England would have thunderstorm and severe weather potential. If it doesn’t shift much, the current area of Marginal Risk denoted by SPC will be the impacted area and this will be updated in future updates. Threat timeframe is 1-8 PM like Friday.

Sunday Afternoon and Evening:
This could be a day where much of Southern New England has severe weather potential but will depend on prior day’s convection, cloud debris, frontal position/triggering mechanism etc. and will be better known as we get to Saturday. Wind shear profiles appear a bit stronger for Sunday. All of Southern New England has a marginal risk for severe weather per SPC. Hazard timing will be better known on Saturday.

While not as hot as earlier in the week, it will still be warm and humid for outdoor activities over the Field Day weekend period so Field Day sites should have plenty of liquids on hand and a place nearby to cool down whether it be a building or cars with AC to stay cool from the heat. Heat tips and safety guidelines are also included in this message. Northeast Massachusetts will have the most relief from the heat Friday into Saturday but the heat will return there as we get into Sunday.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Friday Afternoon and Evening in interior Southern New England for the severe weather and flood potential and possible Saturday through this weekend. SKYWARN Self-Activation will monitor conditions throughout Field Day weekend and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend.

Hello to all..

..This message covers the severe weather potential for Thursday Afternoon and Evening and the thunderstorm/severe weather potential over the Amateur Radio Field Day weekend period.
..Isolated to Scattered Strong to Severe thunderstorms are likely this Thursday Afternoon into early evening across interior Southern New England with the greatest threat over Western, Central and interior Northeast Massachusetts but all of interior Southern New England should monitor the potential. Strong to damaging winds, hail, frequent lightning and heavy downpours with urban and poor drainage flood potential are the main threats.
..The Storm Prediction Center (SPC) has placed Massachusetts from the CT/RI border and Norfolk County north in a slight risk of severe weather with the rest of the region away from the south coast and the Cape and Islands in a marginal risk for severe weather for Thursday. Threat timeframe is between 2-9 PM this Thursday Afternoon and Evening..
..The following is the first in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 20 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program.

Hello to all…

..An intense heat wave continues to affect much of the region away from the immediate coast through Thursday with the intense heat breaking in many areas except for portions of Western Massachusetts and all of Northern Connecticut on Friday though it will still be humid in areas where cooler conditions occur. From a heat perspective, this message is to get the word out on heat safety which is to drink plenty of liquids, take breaks if working outdoors and seek cooler places to avoid heat related illnesses..
..Isolated to Scattered Strong to Severe thunderstorm potential will increase starting Thursday with the Storm Prediction Center (SPC) placing Western Massachusetts in a slight risk for severe weather and much of the rest of Southern New England away from the coast in a marginal risk for severe weather. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats. Timing will be during Thursday Afternoon through early Evening..
..A Heat Advisory is in effect through 7 PM Friday for Northern Connecticut, Hampshire, and Hampden Counties of Massachusetts for heat indices up to 100 expected..
..A Heat Advisory is in effect through 7 PM Thursday for Franklin, Worcester, Middlesex, Essex, Suffolk, Norfolk, North-Central Bristol, North-Central Plymouth Counties of Massachusetts, Providence, Kent and Bristol Counties of Rhode Island for heat indices up to 101 expected..
..Areas outside of the heat advisories will still be warm and humid so taking additional heat precautions would be reasonable to take in these areas..
..Looking ahead, Amateur Radio Field Day weekend takes place Friday through Sunday of this week. At this time, it looks warm and humid but not as hot as during the week but there continues to be the potential for thunderstorms and an attendant lightning risk. Other specifics won’t be known until later this week. Amateur Radio Field Day weather/severe weather coordination messages will be started on Thursday and severe weather potential for Thursday will be covered as part of that message..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible on Thursday Afternoon and Evening for the severe weather and flood potential. Pictures and videos of storm damage can be sent as a reply to this message, via the WX1BOX Facebook and Twitter feeds or via the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

The headlines above depict the current thinking on the heat wave with an earlier ending on Friday for areas away from Northern Connecticut and Western Massachusetts. Heat Safety information is also included this message as the final link in the message.

Turning the attention to the severe weather potential for Thursday, much will depend on a back-door cold front and some cooling aloft to tap into high instability levels. Shear is not very strong but instability will be high and some cooling aloft from the backdoor cold front may allow for some isolated to scattered strong to severe thunderstorms. The greatest risk will be in the interior with northern and western Massachusetts and Northwest Connecticut at a somewhat higher risk. Heavy downpours and flooding may be a bit of a greater threat given the high humidity levels and that will also be monitored. More details on this severe weather potential will be posted either later Wednesday Evening or as part of the Amateur Radio Field Day weather coordination messages will start on Thursday.
